Websumo-kgen¶. sumo-kgen is a program for generating input files containing k-points along high-symmetry k-point paths, for electronic band structure calculations (e.g. KPOINTS file for VASP). The path is unique for each of the 14 Bravais lattice types and, as such, will depend on the symmetry of the unitcell.
